Host stress and immune responses during aerosol challenge of Brown Norway rats with Yersinia pestis
Inhalation exposure models are becoming the preferred method for the comparative study of respiratory infectious diseases due to their resemblance to the natural route of infection. To enable precise delivery of pathogen to the lower respiratory tract in a manner that imposes minimal biosafety risk, nose-only exposure systems have been developed. Early inhalation exposure technology for infecti...
متن کاملImmune system challenge in a host-parasitoid-pathogen system: interaction between Cotesia plutellae (Hym.: Braconidae) and Bacillus thuringiensis influences parasitism and phenoloxidase cascade of Plutella xylostella (Lep.: Plutellidae)
در این پژوهش، اثرات برهم‌کنش بین زنبور پارازیتوئید Cotesia plutellae (Kurdjumov) و باکتریBacillus thuringiensis Berliner بر روی پارازیتیسم و یک مجری سیستم ایمنی (فعالیت آنزیم فنول اکسیداز) جمعیت‌های بید کلم، Plutella xylostella (Linnaeus)، حساس و مقاوم به Btدر آزمایشگاه بررسی گردید. موفقیت پارازیتیسم، بسته به کاربرد Bt یا توکسین آن (Cry1Ac) و همچنین زمان کاربرد آن‌ها، متغیر بود. در جمعیت حساس، ...
متن کاملEffects of Virulence and Fraction 1 antigens from Yersinia pestis on the human innate immune system
Yersinia pestis, the aetiological agent of plague, is responsible for a disease that has killed over 200 million people throughout history and generated three pandemics. This bacterium’s terrible success in causing disease is owed greatly to the virulence factors it expresses. Two of these factors are V antigen (LcrV) and F1 antigen (Caf1), both of which are two major antigens which the immune ...
متن کاملEarly interaction of Yersinia pestis with APCs in the lung.
Despite the importance of pneumonic plague, little is known of the early pulmonary immune responses that occur following inhalation of Yersinia pestis. Therefore, we conducted studies to identify the early target cells for uptake of Y. pestis in the lungs following intratracheal or i.v. inoculation. Following intratracheal inoculation, Y. pestis was rapidly internalized primarily by a distincti...
متن کاملYersinia pestis and plague.
Yersinia pestis is the aetiological agent of plague, a disease of humans that has potentially devastating consequences. Evidence indicates that Y. pestis evolved from Yersinia pseudotuberculosis, an enteric pathogen that normally causes a relatively mild disease. Although Y. pestis is considered to be an obligate pathogen, the lifestyle of this organism is surprisingly complex. The bacteria are...
